' FLU D-PUMP.

To all whom it may concern:

Be it known that I, Ro'BER'r E. NEWCOMB,

a citizen of the United States, residing. at

,Holyoke, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Fluid- Pumps, .of which the following is a specification.

My invention relates to fluid pumps and more especially to that class of pumps wherein pistons are employed WhlCh are moved by means other than mechanical con-' nections,

I am aware to utilize magnetic influence to move the pistons of a pump in a continuous or endless orbit thus providing a. pump which gives a uni-directional flow having a contlnuousv non-pulsating influx to the suction and hkewise a continuous non-pulsating efflux to the discharge, thereby insuring all of the advantages of the usual rotary and centrifugal pumps without the disadvantages of com.-

plex construction and,furthermore, giving I much better efficiency than that of any centrifugal pump An object of the pump constructed according to the present invention is to move'the pistons by the magnetic influence of a rotating magnetic field either ofthe usual r0- tating type or of the .induced type such as occurs in a polyphase induction motor.

In the type of pump here illustrated, pis? tons are confined for movement in one or' more circular or endless pump chambers, and

an electrical magnetic field is employed in connectionwith the pump chambers for moving the pistons in a continuous path around the same. The chamber or chambers is or are provided with inlet and outlet ports for the fluid pumped and between the ports of each chamber is located a device'for retardingthe movement. of each pistounfiiring' its passage between the ports, so that a vacuum will be created between the pisto so retarded and the adjacent, preceding piston,

. thus drawing the fluid into the chamber.

In detail: In the embodiment of the invention illustrated in Figs. 1 and 2, the uxnp comprises a pump casing A having a camber 1 which is in the form of a substantially circular or endless orbitin which a plurality of-pistons .2, 3, 4and 5 move by means to be hereinafter described. The pump chamber 1 has 'an inlet ipe 6 and an outlet pipe- 7, the interiors 0 which communicate with the chamber 1, through ports-8 and 9.

Rotating concentrically with the orbit of movement of the pistons is a rotor B driven by any suitable prime mover and carried on a shaft 11 journ aled in bearings 12. The rotor B isprovided with arms 13' carrying at their outer ends the magnets 14 energized by current supplied thereto by slip rings and 16 fromany extraneous source.

Between the inlet and outletports 8 and '9, respectively, is a stationary magnet 10 which acts to momentarily retard the move ment of each piston during passage between the-two ports and until the adjacent preceding piston has advanced sufliciently to create a vacuum between the two plstonsas,

for instance, in the drawing, the piston 4 has been retarded while the piston 3 is now moving at its usual rate away from the inlet port 8; thus a vacuum is created between the Itwo'pistons .3 and 4 which draws the fluid in through the inlet port 8 and, at the same" time, the piston "5 moving at its usual rate has displaced through the outlet port 9 that bulk of fluid which has been previously drawn in between pistons 4 and 5, and as the piston 2 continues it engages the piston 5 2 and. thus-forces the piston 5 out of range of the influence of the stationary magnet and itself becomes retarded thus repeating the cycle of operations and, in this way, substantially continuous streams of fluid are drawn into and discharged from the casing.

In the type of ump illustrated in Fig. 3, a three phase-seli induced magnetic field is shown at B, which is coiled about the casing A, and an armature B rotates between the inner circumference of the casing, as shown. The armature may be used when desired for the purpose of increasing the influence of the rotating field upon the pistons, which in this instance are three in number and designated 2", 3 and 4". With this construction the pistons are moved similarly to those previously described in connection with Figs. 1 and 2, but by an induced magnetic field in contradistinction to the inoving field previously described.

In the embodiment of the invention illustrated in Figs. 4: and 5, the casing A is shown provided with a plurality of chambers 1 arranged side by side and having common inlet and outlet pipes 6 and 7. The inlet pipe communicates with .both chambers through ports 8 and the outlet pipe communicates with both chambers through ports 9". With this construction, it is obvious that double the amount of fluid will be p'umped as with the pump shown in Figs-1 and 2.

In Figs. 6 and 7, I have shown a multi-.

chamber pump, in which the fluid after be- 4 ing pumped through the chamber 1 is passed through a port 25 into the adjacent chamber l and again im elled in that chamber. This arrangement 0 sections or chambers makes possible a design adapted for high ressure.

While, in the foregoing, I have escribed preferred embodiments of the invention, it

is nevertheless to be understood that, in

practice, I may resort to such modifications as fall within the scope of my invention as hereinafter claimed.
